Re: IML: 67 LeBaron brakes

["Dave Wilker" <wilkerbeast01@xxxxxxxxxxx>]

Just a note...

When I was in Automotive classes, we heard a tale from the instructor about 
a mystery brake problem, Fellow had an International Scout with disk brakes, 
and the pedal would go to the floor. You could pump them up, but it was a 
bit of a pucker factor. So they rebuilt the whole brake system. New 
calipers, pads, all of it. They checked the pedal (after bleeding) in the 
shop and it was high and firm. Customer took it out and almost hit a truck, 
as the pedal went to the floor. Long story short, the rotor bearings were 
bad, so the rotor "wobbled" on the axle, which pushed the piston back into 
the caliper. When the driver hit the brake, the system had to overcome the 
excessive spacing between rotor and pad.

Sometimes, you have to look outside the obvious.

If the brakes don't feel right, there is probably something wrong. Have
them checked by a competent mechanic, or check them very carefully
yourself if you are qualified. In the meantime, don't drive the car
until you are positive that the brakes on the car are working properly.
